The expression is 2x7·5x2
\= 2 · 5 · x7· x2 (Apply commutative property of multiplication: a × b = b × a)
\Since base is common,apply the product of powers property: am·an= am + n.
\= 2 · 5 · x7 + 2
\= 2 · 5 · x9 (Add exponents: 7 + 2 = 9)
\= 10x9 (Multiply: 2 × 5 = 10)
The product of 2x75x2 is 10x9.
